An interesting old school science fiction tale. A page turner for the avid science fiction reader. From the book: Suddenly I became aware of a flickering light above me. I looked up. I had thought that the lights were winking, but they were not. The room was lit by a reading lamp, and the ceiling was so shadowy that at first I could see nothing at all. Then I saw the light-or the ghost of a light-gleaming faintly upon-or through-the ceiling. It was the faintest yellow, neither a bull's eye nor a splotch. Instead, it seemed to be a tiny whirlpool of movement-the faintest nebula in miniature with spirals of light swiftly circling a central core. For a second I thought I could see through the roof, and the stars swarmed before me. It was as though I was at the vortex of a high whirlwind of dancing, shining specks of light. Then that sensation was gone, and there were two faint coiling spirals of yellow light upon the ceiling. The lights began to whisper. (Goodreads)
